MC Hammer is less than thrilled with Kanye West's newest song, 'So Appalled,' and he's taken to Twitter to voice his complaint.

In this week's all-star installment of G.O.O.D. Friday, a weekly promotion from Kanye's G.O.O.D. Music label, 'Ye leaked a song called 'So Appalled,' featuring Jay-Z, RZA, Swizz Beatz, G.O.O.D. artist Pusha T and newcomer Cyhi Da Prynce. The song caught the attention of 'King Hammer' when Jiggaman name-checked the rapper, spitting "And Hammer went broke, so you know I'm more focused/ I lost 30 mil so I spent another 30/ Cause unlike Hammer 30 million can't hurt me."

Hammer quickly jumped on Twitter to attack Jay, whom he referred to as 'HellBoy' and 'Jay-Hoe.' "The answer to Jay comes on Oct 31 (Devils Nite)," Hammer began. "You wanted my attention #HellBoy (Jigga) ... you got it." 'Devils Nite' is apparently a new track Hammer is pegging as a diss track at Jay-Z.

Hammer continued to tweet about the hip-hop mogul's perceived diss, and linked a YouTube clip of himself punching a heavy bag, which you can view here. "Jay-hoe aka #HellBoy Tell Jay Oct 31 (Devils Nite) We'll see if this record and video 'Hurt's Him,' the former millionaire tweeted to Kanye West. "The answer to Jay comes on Oct 31 (Devils Nite) ... I Saw him coming ..."
